A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $800 and the daily rate for each partner is $1800. The law firm designated twice as many partners as associates to the case and was able to charge the client $17600 per day for these lawyers' services. Write a system of equations that could be used to determine the number of associates assigned to the case and the number of partners assigned to the case. Define the variables that you use to write the system.
The equations that could be used to determine the number of associates assigned to the case and the number of partners assigned to the case is: 800 x + 1800 y = 17600.
EquationLet variable x =represent the number of associates, assigned to the case
Let variable y represent number of partners assigned to the case.
The system of equations re:
800 x + 1800 y = 17600
y = x + 2
Plug equation 2 in equation 1, we get,
800 x + 1800(x+ 2) = 17600
2600 x + 3600 = 17,600
Collect like terms
2400 x = 14,000
Divide both side by 2400x
x = 14,000 / 2400
x = 5.8
x = 6 (Approximately)
So,
y = x + 2
y = 5.8 +3
y = 7.8
y = 8 (Approximately)
Therefore the number of associates assigned to the case were 6, and the number of partners associated to the case were 8.

Craig has a job washing cars. He earns $28 for each car he washes. On Monday, he washed 7 cars. On Tuesday, he forgot to count how many cars he washed. He earned $448 for the two days. Josiah wants to find how many cars he washed on Tuesday.
Answer:
9.
he washes 9 cars on Tuesday.
Step-by-step explanation:
28 * 7 = 196.
448 - 196 = 252
252 / 28 = 9
On solving the linear equation 28x + 196 = 448, we get that Craig washed 9 cars on Tuesday.
What is an linear equation in one variable?Linear equation is an equation containing one unknown variable with power one and constants.
The standard form of an linear equation in one variable x is :
ax + b = 0 , where a, b are constants
x= -b/ a is solution if this equation or we can solve this equation by adding or subtracting , multiplying or dividing same number to both sides.
Given that Craig washes cars and earns $ 28 for each car . He washed 7 cars on Monday.
Let on Tuesday he washed x cars
Total money earned on Tuesday and Monday by Craig = $448
Money earned on Monday = $ 7× 28 = $ 196
Money earned on Tuesday = $ x×28 = $ 28x
⇒ 28x + 196 = 448
Subtracting 196 from both sides we get
⇒ 28x + 196 -196 = 448 - 196
⇒ 28 x = 252
Dividing both sides by 28
⇒ x = 252/28 = 9
Therefore, Craig washed 9 cars on Tuesday.

The weight of a person in Venus who weighs 210 pounds on Earth is 185.5 pounds.
It is given in the question that weight of a person on Venus varies directly with his or her weight on Earth. Also, a person weighing 120 pounds on Earth weighs 106 pounds on Venus.
We have to find the weight of the person in Venus who weighs 210 pounds on Earth.
Let weight on Earth be e and,
weight on Venus be v.
From the data given in the question, we can write,
e ∝ v
e = kv
Where k is the constant of proportionality
120 = k*106
k = 120/106 = 60/53
Hence, we can write,
210 = (60/53)*v
(210*53)/60 = v
v = 185.5 pounds

prove that,
b) (a + b)2 = (−a − b)2
c) (a − b)2 = a2 − 2ab + b2
We will prove both of the identities by expanding the exponents, only in the first one we need to use a little trick that is multiplying by (-1)^2 = 1.
How to prove the identities?
Let's start with the first one:
(a + b)^2 = (- a - b)^2
We can start with the left side and write:
(a + b)^2 = (a + b)*(a + b)
Now, remember the rule of signs:
(-1)*(-1) = 1
So we can multiply by one the expression above and get:
(a + b)*(a + b) = (a + b)*(a + b)*1 = (a + b)*(a + b)*(-1)*(-1)
Now we can reorder the product to get:
(a + b)*(a + b)*(-1)*(-1) = (-1)*(a + b)*(-1)*(a + b) = (-a - b)*(-a - b) = (-a - b)^2
So we proved the first part, now the second one:
(a - b)^2
Let's just expand this:
(a - b)^2 = (a - b)*(a - b) = a*a + a*(-b) + (-b)*a + (-b)*(-b) = a^2 - 2ab - b^2

Find the coordinates of J if K(-2, 6) is the midpoint of JL and L has coordinates (-1, -3).
The the coordinates of endpoint J on line segment JL with a midpoint of (-2, 6) is ( -3,15 ).
How determine the a second endpoint from a point and a midpoint?A midpoint is simply a point that divides a line segment into two equal halves.
The midpoint formula is expressed as;
M = ( (x₁+x₂)/2, (y₁+y₂)/2
Given the data in the question;
Midpoint K(-2, 6)
x = -2y = 6Point L(-1, -3).
x₂ = -1y₂ = -3Point J
x₁ = ?y₁ = ?To determine the coordinate of point J, plug the given points into the midpoint formula above and simplify.
First, we get the x-coordinate of point J
x = (x₁+x₂)/2
2x = x₁ + x₂
2( -2 ) = x₁ + ( -1 )
-4 = x₁ - 1
x₁ = -4 + 1
x₁ = -3
Next, we get the y-coordinate of point J
y = (y₁+y₂)/2
2y = y₁ + y₂
2(6) = y₁ + (-3)
12 = y₁ - 3
y₁ = 12 + 3
y₁ = 15
Therefore, the coordinates (x₁,y₁) of the endpoint point J is ( -3,15).

Mason and his children went into a movie theater and he bought $36.50
worth of candies and pretzels. Each candy costs $4.25 and each pretzel costs
$3.50. He bought 6 more pretzels than candies. Write a system of equations
that could be used to determine the number of candies and the number of
pretzels that Mason bought. Define the variables that you use to write the
system.
Answer:
4.25c + 3.5p = 36.50
c + 6 = p
c = candies and p = pretzels
Step-by-step explanation:
So for the first equation, the prices will be the coefficients of each variable, since for each candy/pretzel it will be that price. We also know that both of these prices together equal 36.50, so that will be on the other side of the equal sign. So the equation representing this info is 4.25c + 3.5p = 36.50
And for the second equation I saw that Mason bought 6 more pretzels than candies. So no matter what number the candies is, the pretzels should always be 6 more than the candies. So the equation representing this information is c + 6 = p
Lastly I just defined the variables that I used to right the system. That is all! Hope this helps you this should be correct :)

First, we will determine the slope of the line
Using the points (1, -5) and (3, -4)
From the formula,
Slope = (y₂ - y₁) / (x₂ - x₁)
Slope = (-4 - -5) / (3 - 1)
Slope = ( -4 + 5) / 2
Slope = 1/2
Now,
For the point-slope form of the line
Using the point-slope form of the equation of a straight line,
y - y₁ = m(x - x₁)
Where m is the slope
The given point is (5, -3)

How to determine the polynomial equation?The given parameters are
Degree of polynomial = 4Zeros = -3, 4 and 6−3 is a zero of multiplicity 2The sum of multiplicities of the polynomial equation must be equal to the degree.
This means that the multiplicity of the zeros 4 and 6 is 1
The equation of the polynomial is then calculated as
P(x) = (x - zero)^ multiplicity
So, we have
P(x) = (x - (-3))² * (x - 4) * (x - 6)
This gives
P(x) = (x - 4)(x - 6)(x + 3)²
